MINI-LINK TN R3 ETSI
MMU2 B and MMU2 C have the same functionality regarding mechanics and
interfaces. However, there is an important difference when it comes to RAU
compatibility:
•
•
MMU2 D is not compatible with MMU2 B or MMU2 C, that is it can not be
combined with MMU2 B or MMU2 C in a 1+0 or 1+1 hop. MMU2 D can be
placed in the same AMM as MMU2 B or MMU2 C but can not be part of the
same radio terminal.
Figure 56
MMU2 E 155 and MMU2 F 155 have the same functionality regarding
mechanics and interfaces except for XPIC support on MMU2 F 155. MMU2 E
155 and MMU2 F 155 are compatible with both RAU2 N and RAU2 X. For the
STM-1 interface a Small Form Factor Pluggable (SFP) is needed. The SFP can
be either electrical (SFPe) or optical (SFPo), see Section 7.3 on page 128.

MMU2 B and MMU2 C in C-QPSK mode are compatible with RAU1, RAU2,
RAU1 N and RAU2 N.
MMU2 C in 16 QAM mode is compatible with RAU1 N and RAU2 N.
